DAVID T. PICKLES, OF WASHINGTON, N ORTH CAROLINA.

FLUSH-TANK VALVE.

To all whom 2'27 may concern:

Be it known that I, DAVID T. PICKLES, a citizen of the United States,'residing at WVashington, in the county of Beaufort and State of. North Carolina, have invented certain new and useful Improvements in Flush- Tank Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in flush tank valves.

The object of the present invention is to improve the construction of flush tank valves and to provide a simple, inexpensive and efficient flush tank valve designed to eliminate the ordinary rubber bulb and to provide a construction which will not be materially affected by the chemical action of the water of any section of the country whereby the durability of flush tank valves will be greatly increased. I

A further object of the invention is to provide a flush tank valve adapted to employ aglass bulb of the general form of an ordinary forty watt electric lamp so that burnt out electric lamps may be employed as flush tank balls when desired.

lVith these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out shown applied to a portion of a flush tank,

Fig. 2 is a horizontal sectional view on line 2-2 of Fig. 1, Fig. 3 is an enlarged detail sectional view illustrating the construction of the valve seat, Fig. 4 is a detail view of the valve guide.

Like numerals of reference designate corresponding parts in all the figures of the drawing. y

In the accompanying drawing in which is illustrated the preferred embodiment of the invention, 1 designates an outlet pipe extending through the bottom. 2 of a flush tank Specification of Letters Patent.

and having a threaded portion 3 receiving a lock nut 4 for clamping it to the bottom of the flush tank, a rubber gasket 5 of the ordinary construction being interposed between the lock nut and the bottom of the flush tank. The threaded portion of the outlet pipe is adapted to be coupled in the usual manner to the flush pipe leading from the annular is spaced from the inner wall of the outlet or outlet pipe 1 and it is eXteriorly threaded at 12 for the reception of a guide consisting of a disk or ring 13 and four vertical posts 13 and adapted to clamp a valve seat 14: on the upper enlarged portion of the outlet. The posts 13 are adapted to guide a valve 15 to the seat 14 and they and the disk 13 are constructed of any suitable material and the disk or ring 1 is provided at its lower end with an interior annular recess 16 forming an upper shoulder 17 which engages over the upper face of the valve seat 14 and clamps the same firmly in position. The valve seat 14: which is designed to be constructed of soft material such as rubber, lead, fiber, vulcanized rubber or the like to enable the valve 15 which is constructed of glass to seat itself without breaking is provided at its upper and lower faces with corrugations 18 of annular form to provide a water tight connection or joint and prevent any leakage at that point. The valve seat has a concaved valve receiving face 19 and it is in the form of a washer or gasket and is adapted tobe readily replaced when necessary, The valve 15 which consists of a bulb of the same shape as a forty watt electric lamp has a threaded neck 20 for the reception of a threaded cap 21 which is also provided with a central threaded socket 22 into .which screws the lower threaded end 23 of a rod or stem 24 and the latter is guided in a vertical sleeve of a horizontal arm 26. The arm 26 is provided at its inner end with a set collar 27 which is adjustably secured on the overflow pipe or tube by a set screw 28. The upper end 29 of the valve rod or sufficiently heavy to prevent any liability of accidental breakage or breakage during the ordinary operation of the flush tank valve and as the valve seat may be constructed of any material sufficiently soft to coact with the bulb valve and of a character not to be affected by any chemical action of the water, a flush tank valve of great durability is provided and the cost thereof will be considerably less than the rubber bulbs ordinarily employed and will not require such frequent replacement. Also when the valve seat or gasket is constructed of rubber only a small portion of rubber is exposed to the action of the water and it may be replaced when necessary without troubleand at an exceedingly low cost without liability of causing any leakage at the valve seat.

What is claimed is 1. A flush tank valve including an outlet pipe provided with an annular flange exteriorly threaded and spaced fromthe passage of the outlet pipe, a valve seat arranged within the flange, a vertical valve guide pro vided at its lower end with a recess, and

interiorly threaded thereto to engage the said flange, said recess forming a shoulder and the latter extending over the flange and engaging the valve seat to retain the latter in place and a valve guided by the said guide and coacting with the valve seat.

2. A flush tank valve including an outlet pipe designed to extend through the bottom of a flush tank and provided at the top with an annular flange having exterior threads and spaced from the passage of theoutlet pipe, a valve seat arranged on the upper end. of the outlet pipe and fitted within the said flange and provided with annular corrugations located at the upper and lower faces of the said valve seat and interiorly threaded guiding means engaging the threaded flange and provided with a shoulder extending over the same and engaging the valve seat to hold the same in position;

3. A'flush tank valve including an outlet comprising a circularvbottom portion se-,

cured to the said flange and extending over the same and engagingthevalve seat and provided with spaced upwardly projecting posts and a valve guided by the said posts.
